Es prediction of DM3MAT propagation

Jav, ktorý využíva lovci DX signálov… áno, sporadická E, tzv. Es vrstva. Každý, kto ju zažil potvrdí, že sú to také Vianoce rádioamatéra. Akurát nikto nevie presne kedy tieto rádioamatérske sviatky prídu. DM3MAT si vytvoril pre JO62 online predpoveď v pásmach 10m a 6m. Je založená na živých spotoch WSPR in these bands. The prediction algorithm attempts to estimate the lower bound of the critical frequency in Europe derived from the WSPR points. A simple model, the so-called tide and wind. This model is not able to predict the occurrence of Es events in advance, but it will give information about extraordinary propagation conditions. The web address is https://dm3mat.darc.de/spore/
